The reason why walking with an ethnic in public can boost your perceived status as a white man

[6ft4]

If you are in a 95%+ white area where seeing ethnics isn't common, occasionally walking with an ethnic can make people perceive you as higher status because their brain subconsiously believes you are a slave owner commanding your slave to follow and serve you which makes you look high status since wealthy people are more likely to have slaves

Just hire an ethnic as your assistant, dress him in exotic clothes and people will think you're rich and powerful.
